Find LCM of 663,476,357,990 with Prime Factorization
| 2 | 663, 476, 357, 990 |
| 3 | 663, 238, 357, 495 |
| 7 | 221, 238, 119, 165 |
| 17 | 221, 34, 17, 165 |
| 13, 2, 1, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 13 x 2 x 1 x 165 = 3063060
Therefore, the lowest common multiple of 663,476,357,990 is 3063060.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
663 x 476 x 357 x 990 = 111538266840
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
663 : 1, 3, 13, 17, 39, 51, 221, 663
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
357 : 1, 3, 7, 17, 21, 51, 119, 357
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,476,357,990, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
476:2x 2x 7x 17
357:3x 7x 17
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 17x 17 = 36414
Therefore, the value for common factors is 36414.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 111538266840/(1x36414)
LCM = 111538266840/36414
LCM = 3063060
Thus, we can understand that the LCM of 663,476,357,990 is 3063060.
